Do not float the ILIM pin or damage to the device is possible. Connect ILIM directly to V− to program the maximum output current limit, typically 1.2 A. The simplest method for adjusting the current limit (ILIM) uses a resistor or potentiometer connected between the ILIM pin and V− according to the following equation:
This external resistor determines a small internal current which sets the desired output current limit. Alternatively, the output current limit can be set by applying a voltage to the ILIM pin. Figure 6-1 shows a simplified schematic of the OPA561 current limit.
